The Regulator is the piece marked “+” and “-“.

It slightly lengthens or shortens the hairspring to make the watch run slower or faster. When a watch is dirty or has some other problem keeping it from operating correctly, poor timing can be compensated by over adjusting the regulator to cancel out the effects of the other issues.
This is only a temporary fix and should be looked at by a competent watchmaker as soon as possible.
Gerard Perregaux was (and still is) a very fine watch company. Timex was (and still is) a mass market brand. Impossible to compare them on an equivalent basis.
